When shall a proper look-out be maintained?

A proper look-out must be maintained at all times to ensure the safety of vessels on the water. This requirement is fundamental to the Rules of the Road, as it helps in detecting other vessels, navigational hazards, or other potential dangers that could affect safe navigation. A vigilant watch keeps the crew informed about the surrounding environment, allowing them to respond promptly to any unforeseen situation.

While maintaining a look-out is especially critical during dawn, dusk, or reduced visibility conditions, these times are not exclusive scenarios; hazards can arise at any moment. By adhering to the practice of maintaining a proper look-out continuously, mariners ensure a greater level of safety and readiness, which is imperative in a constantly changing maritime environment.

In contrast, maintaining a look-out only during specific times or situations, such as just in narrow channels or when visibility is low, does not provide sufficient precaution against potential collisions or accidents that could occur under various circumstances.
